The discovered model are appraised against exact solution derived by the amplitude mapping closure (AMC)/ Johnsohn-Edgeworth translation (JET) model of binary scalar mixing in homogeneous turbulence. Recently, the deep learning techniques have enhanced the methods for diffusion prediction and provide a new way to model the diffusion process in time and space. There are two kinds of models in Deep Learning. This learning-based approach is in marked contrast to classical methods with a physical interpretation of the process for both computational modelling of data given a physical model (which we call a forward problem) and the estimation of parameters of a physical model from measured, usually noisy, data (which we call an inverse problem).Several recent papers have discussed the application of .
